Tropical Depression LINDA


ZCZC MIATCDEP5 ALL
TTAA00 KNHC DDHHMM
TROPICAL DEPRESSION LINDA DISCUSSION NUMBER  20
NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL   EP152009
800 PM PDT FRI SEP 11 2009
 
DESPITE MAINTAINING A RELATIVELY WELL-DEFINED CIRCULATION OF LOW AND
MID LEVEL CLOUDS...LINDA HAS BEEN ABSENT OF ORGANIZED DEEP
CONVECTION FOR WELL OVER 12 HOURS AND THEREFORE NO LONGER MEETS THE
CRITERIA TO BE A TROPICAL CYCLONE. AS A RESULT...THIS WILL BE THE
LAST ADVISORY ON LINDA. THE INITIAL INTENSITY IS LOWERED TO 30 KT
BASED ON SATELLITE IMAGERY AND THE CYCLONE SHOULD CONTINUE TO WIND
DOWN AND ULTIMATELY OPEN UP INTO A TROUGH IN 3 DAYS...OR LESS.
 
THE INITIAL MOTION ESTIMATE IS 300/04 KT. THE SHALLOW LOW IS
EXPECTED TO MOVE IN A GENERAL WEST-NORTHWESTWARD DIRECTION DURING
THE NEXT 24-36 HOURS WITHIN THE FLOW ALONG THE SOUTHEASTERN
PERIPHERY A LOW-LEVEL RIDGE TO THE NORTHWEST AND A CUT-OFF LOW TO
THE NORTH-NORTHEAST. AFTERWARD...IF THE SYSTEM HAS NOT BECOME AN
OPEN TROUGH...IT SHOULD BEGIN A TO TURN MORE TOWARD THE NORTHWEST IN
RESPONSE TO A DEVELOPING WEAKNESS IN THE RIDGE. THE OFFICIAL NHC
TRACK FORECAST IS SIMILAR TO THE PREVIOUS ADVISORY AND IS BASED ON
THE TVCN MODEL CONSENSUS.

FOR ADDITIONAL INFORMATION ON THE REMNANT LOW PLEASE SEE HIGH 
SEAS FORECASTS ISSUED BY THE NATIONAL WEATHER SERVICE...UNDER 
AWIPS HEADER NFDHSFEPI AND WMO HEADER FZPN02 KWBC.
